Helifix repair and reinforcement products, with their concealed non-disruptive installation techniques,

help to preserve our built environment. They secure and strengthen all masonry structures, from

houses and offices to factories and heritage sites. Our innovative systems not only restore structural

integrity in weakened masonry by overcoming virtually all commonly occurring faults, they can also be

used to improve the existing performance of our buildings, offering increased protection against

seismic activity and other movement threats.

Wherever possible, repair and refurbishment is increasingly seen as a more sustainable option than

demolition in terms of architectural value, materials usage, overall cost and environmental impact.

Management buy-out of Helifix

from the original shareholders.

until 1984, when the Building research

establishment (uK) published a paper on

the ‘Performance specification for Wall ties’,

there had been no examination of the

performance requirements of wall ties and

no basis for their design and testing. Mild

steel twist ties were weak and subject to

corrosion, while remedial ties were based

on masonry fixings and in many cases were

often ineffective or, due to their rigidity,

actually caused further masonry damage by

creating additional stresses and cracking.

recognising the need for a purpose-

designed wall tie, Helifix engineered an

entirely new style of remedial tie, using

austenitic stainless steel, with a unique

helical shape. A non-expansion mechanical

resin fixing, this new tie was very strong

axially, to resist wind suction, yet sufficiently

flexible to accommodate natural building

movement, introducing no additional

stresses by avoiding expansion.

An on-going programme of research

and development has, over the years,

produced a variety of innovative ties, fixings

and repair systems. these include: retrotie,

the first stainless steel remedial helical wall

tie; inskew, a high performance, self-tapping

warm roof batten fixing; turboFast, a multi-

purpose timber to masonry flush fixing;

dryFix, a rapidly installed remedial wall tie,

requiring no grouts, resins or mechanical

expansion, that uses a specially developed

power-driven tool for a recessed installation;

the Helibeam system of structural beaming,

using existing masonry, that reinforces the

structure, spreads loads and minimises the

need for mass underpinning.

All Helifix products have undergone

extensive independent testing at universities

in the uK, Australia, New Zealand and

around the world, and at well recognised

bodies such as the Bre, trAdA and the

trl. Full details of the complete test

programme are available on our website.

Furthermore, Helifix products are

manufactured to exacting standards in

Helifix’s uK factory, under the isO 9001

quality assurance scheme, ensuring high

levels of quality control and traceability.

research and development

RESIDENTIAL

Helifix systems can be applied to a range of

problems that often trouble residential

buildings, including masonry cracking, failed

wall ties, sagging lintels, bowing and

separated walls, and subsidence related

problems.

Masonry cracking and failure have many

causes, and may contribute to problems

varying from the purely aesthetic to

structural, so it is important that the cause is

identified and the design and

implementation of appropriate remedial

work is carried out.

BRIDGES AND TUNNELS

seismic events, age, weathering and

increasing loads and stresses have, in

numerous cases, led to problems on many

masonry arch bridges and tunnels around

Australasia. Many are historic structures and

urgently require structural repairs and

strengthening.

Following extensive research at the trl in

the uK, Helifix has developed a range of

innovative solutions for the maintenance

and strengthening of brick and stone

masonry bridges, viaducts and tunnels.

HISTORIC STRUCTURES

Historic and listed buildings require reliable

and sympathetic solutions that leave the

structure secured but visually unaltered.

Helifix has considerable experience of

working with conservation professionals and

bodies and on projects involving lime

mortars, weak and unusual materials.

Helifix solutions retain the existing masonry

and, due to the fully concealed nature of the

products, leave the structure visually

unmarked.

Applications

Helifix remedial products are extremely versatile and have

wide ranging applications. this means that individually or

in combination they are able to provide rapid, reliable and

cost-effective solutions to virtually all commonly occurring

structural faults. Furthermore they do so in a sympathetic

and non-disruptive manner that leaves the structure visually

unaltered but fully stabilised.

Full details of all applications and repairs are available at: www.helifix.com.au and www.helifix.co.nz



APPliCAtioNS

Crack stitchingHelifix crack stitching provides a quick, simple, effective and permanent means of stabilising

cracked masonry. installation involves bonding stainless steel HeliBars into appropriate bed

joints or cut slots in bricks, blocks or stonework, using HeliBond cementitious grout.

HeliBar and HeliBond combine to produce an excellent bond within the substrate, resisting

tensile loads and minimising any future development of the crack, which may occur with simple

injection methods. With this concealed non-disruptive method no additional stresses are

introduced as the HeliBars are flexible enough to accommodate normal building movement.

Retrofitting wall tiesWall tie failure and inadequacy, if not addressed, can lead to catastrophic collapse. Wall tie

corrosion is a common cause of wall tie failure in coastal areas. Walls suffering from failed,

omitted or inadequate wall tie systems are most vulnerable during high winds and seismic

events.

there are Helifix remedial ties for all situations and materials. dryFix ties are probably the

quickest and most cost-effective ties available. requiring no grouts or resins, they are simply

power-driven into both leaves, via a small pilot hole, using a special attachment which leaves the

tie recessed below the face. retroties are dry-fixed in the far leaf and resin bonded at the

outer end and resities are resin-bonded at both ends.

easy external installation means minimal inconvenience for the occupants while providing an

unobtrusive connection with no external plates. standard Bowties are used when securing

the wall into joist ends and Bowties Hds when mechanically connecting to two or three

parallel joists. the Bowtie is inserted through a clearance hole in the wall and power-driven

into position before being resin bonded into the masonry.

Reconnecting separated wallsCracked internal walls which have separated from the main outer walls can be repaired and

reconnected both internally and externally.

From the exterior, long series grouted Cemties are installed, at a slight angle, through the

external brick or stone wall and into the internal wall, stitching cracks and holding the two

walls together. internal repairs involve drilling angled clearance holes into the exterior wall at

the junction of the two walls into which HeliBar ends are bonded before being grouted into

cut slots along the internal wall.

Creating masonry beamsthe Helibeam system uses pairs of long HeliBars bonded with HeliBond grout into cut slots

to form deep masonry beams from the existing masonry. these masonry beams reinforce

and stabilise the existing masonry while redistributing the structural loads. their composite

action provides great strength combined with structural flexibility, while other ties and fixings

provide appropriate lateral and vertical restraint.

Helibeam creation is fast and uncomplicated and used to add strength, ductility and resilience

to unreinforced masonry. Beams may be created to provide structural support to failed

lintels, unstable, weak, vulnerable or weathered masonry, or masonry stressed by building

subsidence.

Adding strength and ductilityimproving the ability of buildings and building elements to deform without collapsing is an

important part of seismic strengthening programmes. HeliBar bonded with HeliBond grout

into slots cut into masonry can help improve ductility by holding the masonry together and

distributing stresses over larger areas.

HeliBar installation is fast and uncomplicated, and requires minimal disruption and

architectural alteration. HeliBars are manufactured from stainless steel for high corrosion

resistence, and may be bent and manipulated on site to provide additional anchorage where

required and to follow contours and corners. the Hi-Fin helical profile ensures excellent

mechanical bonding with HeliBond cementitious gout over short distances.

Products required: HeliBar - page 18

Securing Parapet Wallsthere are multiple parapet wall constructions, on building roofs and bridges,

with both cavity and solid walls being common. if they are cracked or unstable they can be

repaired, strengthened and reconnected using a combination of Helifix remedial products.

Generally, masonry beams are created using the existing substrate, even on curved parapets,

together with lateral masonry tying. in addition, grouted Cemties are normally installed

vertically down through the coping stones into both masonry leaves and at an angle though

the wall to secure it to the roof or bridge deck.

Tying veneers to new structural wallsWalls may need to be replaced and others added to achieve numerous objectives. in many

cases, internal or structural masonry walls may need to be replaced or strengthened to

improve seismic performance.

Helifix remedial ties are effective in bricks, blocks, concrete, hard mortar and timber and can

be used to tie a variety of different materials together. dryFix ties, for instance, can be used to

tie timber to masonry or masonry to new structural concrete.

Helifix ties and fixings are made from high tensile Grade 304

or 316 stainless steel to a unique helical design. this creates a

slim profile with a large surface area that ensures a secure and

lasting connection, with or without grouts or resins, in bricks,

blocks, stone, concrete and timber as well as local building

materials. it also means all products have great axial strength

combined with flexibility which allows natural structural

movement and avoids the introduction of any additional

HeliBars provide substantial tensile

properties to masonry when bonded with

HeliBond grout, which is able to lock tightly

between the fins and to the masonry.

Consequently, HeliBars have a variety of

remedial and new build applications.

• Crack stitching

• Forming deep masonry beams

• tying corners and wall junctions

• reconnecting separated walls

• lintel stabilisation and creation

• Horizontal structural restraint

• reinforcing new build masonry

• Providing seismic upgrades

PRoduCtS



Crack StitchingCrack Stitching is a method of repairing

and stabilising cracked masonry using

HeliBars bonded into cut slots with

HeliBond cementitious grout.

Masonry may move and crack as a result of

movement in foundation soils, seismic

activity and cyclical wet and dry, hot and

cold environmental conditions. Crack

stitching reintroduces structural integrity

and redistributes structural loads for a quick,

simple, effective and permanent solution.

• Quick, simple, effective and permanent

• More effective in brick/block masonry than

simple crack injection

• suitable for all types of masonry including

listed and historic structures and those with

lime mortar

• Fully concealed, non-disruptive repair

system

• stainless steel HeliBars and non-shrink

HeliBond grout combine to create excellent

tensile strength within the masonry

• tensile loads are redistributed along the

masonry

• Masonry remains flexible enough to

accommodate natural building movement

d. HeliBar to be long enough to extend a minimum of 500mm either side of the crack or 500mm beyond

the outer cracks if two or more adjacent cracks are being stitched using one rod.

e. For solid masonry in excess of 230mm and in a cavity wall where both leaves are cracked, the wall must

be crack stitched on both sides.

f. Where a crack is less than 500mm from the end of a wall or an opening, the HeliBar is to be continued

for at least 200mm around the corner and bonded into the adjoining wall or bent back and fixed into

the reveal, avoiding any dPC.

Method Statement1. using an appropriate power cutting tool with vacuum attachment, cut slots

into the horizontal mortar joints, to the specified depth and at the requiredvertical spacing.* ensure that as much mortar is removed as possible fromthe exposed brick surfaces in order to provide a good masonry/grout bond.

2. Clean out all dust and loose mortar from the slots and thoroughly flush withwater. Where the substrate is very porous or flushing with water isinappropriate, use HeliPrimer Wb. ensure the slot is damp or primed priorto commencing step 5.

3. Mix Helibond cementitious grout thoroughly using a drill and mixing paddleand load into the Helifix Pointing Gun.

4. fit the mortar nozzle to the pointing gun.

5. inject a bead of Helibond grout, 10-15mm deep, into the back of the slot.

6. Push the Helibar into the grout to obtain good coverage.

7. inject a second bead of Helibond grout over the exposed Helibar and ironit into the slot using a finger trowel. inject additional Helibond as necessary,leaving 10-15mm for new pointing.

8. Point up the remaining slot with a suitable matching mortar. the crack withinthe wall should be waterproofed using an appropriate Helifix bonding agentor filler, e.g. Helibond or Crackbond, depending on the width of the crackand the surface made good or left ready for any decoration.

9. Clean tools with clean, fresh water.

Note. Pointing may be carried out as soon as is convenient after theHelibond has started to gel. ensure that pointing does not disturb themasonry/Helibond connection.

CAutioN. Always locate, identify and isolate any electrical, water orgas services which may be present in the wall or the wall cavities andcan pose a safety risk before drilling or cutting.

A. this detail and the associated load table relate to tied arch (concealed

lintel) construction using clay masonry only. Alternative build methods

and specifications may be required for the construction of lintels using

concrete, AAC or any other cement-based masonry bricks or blocks

which are prone to shrinkage over time.

b. A reinforcement pattern which takes into account the individual

circumstances and requirements, and which adheres to the guidelines

provided by the sAA Masonry Code As3700-2001, must be specified

and followed for each situation involving the installation of HeliBars into

new masonry. the load table presented on the following page may be

used as a guide to the specification of tied arches design in accordance

with the Australian masonry codes.

C. the HeliBar should be embedded in the mor tar of the specified

courses, either 2, 3 or 4 rods per bed, as construction progresses.

d. the beams should be built in situ and should not be moved or knocked.

e. it is critical that the HeliBars are fully embedded in the mortar during

construction. they should not be moved or loosened once the mortar

has been laid.

f. Minimum mortar strength type M3 (C1: l1: s5) in accordance with the

masonry code. Bond strength is critical and the use of air entraining

agents or other additives likely to reduce bond strength is to be avoided.

For increased workability of the mortar a cellulose-type thickener such

as ‘dynex’ may be used in accordance with the manufacturer’s

instructions.

G. the Helibeam must not be broken by flashings, damp-proof courses or

weep holes.

H. in high ambient temperatures (above 25°C) do the following

improvements in the performance of the reinforced masonry.

C. HeliBar reinforcement contributes to the strength of the masonry in

both the uncracked and cracked state. Masonry only acts as reinforced

masonry when some deflection and micro cracking of the masonry has

occurred, permitting the steel reinforcement to take effect. this design table

limits the deflection to less than span/300. Further reduction of deflection

and micro cracking can be achieved by using additional HeliBars.

d. For design purposes the characteristic tensile strength (fsy) of the

reinforcement is taken as 700MP.

e. loads shown satisfy both design Moment and design shear.
